2, the basic items: 1) the total area of ??each paste extruded board with grass surface is 30-50% 2) The holder of the plug partially into the structure of the wall is not less than 50.3) extruded board does not wipe the adhesive seam meet agent. Prolonged use, not aging, decomposition, no harmful substances, the chemical properties of extremely stable extruded insulation material, not as a result of corrosion due to water absorption and degradation to performance degradation of insulation materials under high temperature environment can still to maintain its superior performance, according to the information retardant insulation materials, XPS extruded insulation board even with 30 to 40 years, can still maintain excellent performance, and will not decompose or mildew, no volatile toxic substances.
